Fig. 143.—Deformity of upper extremity andthorax after poliomyelitis anterior acuta. frequently encountered wasting is in the small muscles of the hands, thedeltoid, and the extensors of the wrists. The biceps and supinatorsgenerally escape. The distribution of the paralysis of muscles follows their segmentalrelations in the cord, and, consequently, when limited is of a functionalcharacter. The very fact of such functional distribution at once incrimi-nates the cord. The muscles of the trunk are in rare cases notably andwidely affected, producing weakness in the back, deviation of the spinalcolumn, and defects in the muscles of the chest. Ordinarily, however,the segments of the cervical and lumbar enlargements are selected. Asmall focus of anterior poliomyelitis in the dorsal region hardly pro-duces local signs, as the trunk and thoracic muscles are represented in a 390 DISEASES OF THE CORD PROPER. considerable vertical
